Discovering Discharges After Prayer
• If you are certain that the discharge came out while you were praying, or before you prayed [and after you did Wudu], then your prayer is invalid, and you have to clean yourself, purify your clothing and body of whatever got onto them, and do Wudu again and repeat the prayer. • If you are not sure whether the discharge came out while you were praying, or before or after that, then you do not have to repeat anything, because the basic principle is that you started praying in a state of purity, and the prayer cannot be deemed invalid on the basis of mere uncertainty.
